Distribution into primary and secondary tumors, as well as the type of analysis performed, is indicated. Seven low-risk cases with later progression were included and marked with asterisk*. All other tumors were high-risk, or recurrence after high-risk tumors. Detailed clinical information about all individual cases including primary and current stage, grade, treatment, CIS-status, progression free survival, metastases, overall survival and causes of death are listed in Additional File 1.
